Sec and putting him in chains. Dalek Caan took control and fuelled the other human bodies with pure Dalek DNA. Sec opposed their attempt to kill the Doctor, warning the others that "If you choose death and destruction... then death and destruction will choose you." The Daleks dismissed this thought, arguing that they "always survive", and killed their former leader when he tried to protect the Doctor. The Doctor showed his respect for Sec by calling him the "cleverest Dalek ever" and the only one who could have led the Daleks "from the darkness." Due to his hybridization from Dalek to Human Dalek, Dalek Sec has been the first Dalek to repent the deaths he caused (Dalek Caan being the second), and the only Dalek who willingly sacrificed himself to save the Doctor. His character as a Dalek/Human hybrid is not entirely clear, as, although he eventually feels humanity, it is sometimes also implied that he still had plans to cause destruction. An example would be when Dalek Caan becomes 'controller' of the Human Daleks and plugged into their military computer; Sec responds to this act of treachery with "That was to be my position!" Sec was the first Dalek of the new series to have its mutant seen while in a healthy state (with a possible exception of the Dalek Emperor). He was also the first Dalek in the new series to open its lower casing as well, showing longer tentacles. Sec was also shown to be able to engulf Mr. Diagoras in a sack-like membrane projected from what appears to be his mouth parts. His "skin" had a dark-greenish color to it as well. According to the Doctor Who Files book on the Cult Of Skaro, Dalek Sec was the Commander of the Seventh Incursion Squad and led the attack on the Mechonoids on Magella before being promoted by the Dalek Emperor. Dalek Caan Dalek Caan was originally second in command to Dalek Sec, whom he overthrew after Sec became a Human/Dalek hybrid. He has the lowest pitched voice in the Cult, and is the most prominent Dalek of the revived series (having appeared in a total of six episodes). According to the Doctor Who Files book on the Cult of Skaro, Caan was once an Attack Squad Leader in the Thirteenth Assault Group before being promoted by the Emperor. He fought in the Battle of Canary Wharf,
